Communication across public networks is more than a convenience; it’s a necessity. Use Futurex’s strong encryption and authentication to ensure your transmitted data is always secure.

A Framework for Safe Communication

Global communication is increasing at an extraordinary rate, and that communication often involves sensitive data that proves a valuable target for malicious entities. In order to ensure that data is only accessible by authorized individuals, the most secure solution is a public key infrastructure (PKI). PKI is a technology involving asymmetric encryption, in which certificates comprised of public and private keys are used for both the encryption and decryption of information.

The public key cannot decrypt data, only encrypt it, and so it can be widely distributed to anyone without fear of exposing sensitive data. The private key must be kept highly secure as it is used to decrypt the data that was encrypted by the public key. These asymmetric keys are created by a device called a certificate authority, which is capable of managing entire trees of keys and certificates from trusted roots all the way down to individual keys injected into devices.

Establishing PKI

The first step to creating a PKI is to use the certificate authority to create a certificate tree. Starting with a highly secure root certificate, a hierarchy of new certificates is created beneath it, and these certificates are distributed to individual devices, users, or objects that need to be part of the line of secure communication. By using the same certificate authority to distribute certificates to all devices within a network, that system becomes a circle of trust for mutually authenticated communication.

When parties wish to communicate securely, they begin by exchanging public keys. Each party uses the public key they received from their partner to encrypt the message, then sends that encrypted value to the other person. Once that value is received, it is decrypted with the private key corresponding to the public key that encrypted the message. This process allows for information to be shared easily while maintaining full security, because if the message is intercepted, it will be unreadable due to encryption.

The devices within Futurex’s Hardened Enterprise Security Platform are designed to provide organizations with all the functionality they need to establish and maintain a secure public key infrastructure. This encompasses processes such as:

Futurex’s key management servers have support for the entire key and certificate lifecycle, providing protection and functionality from initial generation to end of life decommission, and everything in between. This cradle to grave approach allows organizations to use a single solution for all of their encryption key processes, without having to sacrifice security or flexibility by integrating multiple devices or vendors in order to achieve the same functionality.
